    Ficus macrophylla


    The EBOP (UNDATED) states that, "F. rubiginosa can be identified from Morton Bay fig (Ficus macrophylla) by the smaller, hairy leaves, and smaller fruit." The two species are quite easy to separate at a glance. F. macrophylla has much larger syconia of 18 - 26 mm long and 15 - 24 mm diameter (compared to 7.4 - 17.3 mm long and 7.6 - 17.3 mm diameter for F. rubiginosa) that have distinctive pale spots when mature (Dixon 2001). The darker green adaxial lamina surface contrasts strongly with the lighter green abaxial surface with its distinctive ferruginous hairs. While the two species have some overlap in leaf morphology, F. macrophylla usually has considerably larger leaves and longer petioles. F. macrophylla has expanded its Australian range to urban areas of South Australia, Victoria and Western Australia (McPherson 2004), and has naturalised in New Zealand (Gardner and Early 1996, Early 2000) and Hawai'i (PIER 2005).
    Ficus obliqua


    Ficus obliqua has ascending hyaline on the petiole and the lamina surface is always glabrous. F. rubiginosa has both lamina and petiole with ascending hyaline hairs or both lamina and petiole with ferruginous hairs or a combination of hyaline and ferruginous hairs on both lamina and petiole or both lamina and petiole are glabrous. F. obliqua syconia are usually smaller being 4.3 - 11.9 mm long and 4.4 - 11.0 mm diameter compared to 7.4 - 17.3 mm long and 7.6 - 17.3 mm diameter for F. rubiginosa (Dixon et al. 2001). F. obliqua is invasive in urban areas of south east Queensland, which are within its historical range (McPherson 2004). It is not widely cultivated outside this area and thus unlikely to support populations of its pollinator.
    Ficus watkinsiana


    Vegetatively both species are similar. Ficus watkinsiana has syconia that are 24–37 mm long, 18–29 mm in diameter, that are deep purple to black when ripe and has a peduncle 9–25 mm long (Dixon 2003). F. rubiginosa has syconia 7.4-17.3 mm long, 7.6-17.3 mm diameter, that are red, orange, yellow, orange-brown, red-brown, pink or purple when ripe and has a peduncle 1.2-19.0 mm long (Dixon et al. 2001). F. watkinsiana seems not to fare well outside complex vine forests on richer soils (McPherson 2004).
